On my stock '95 PS190, TBI my fuel pump (electric), is in-line at the rear of my motor, between the stringers. The pump is $250.00 new. My system runs a return line from the pump back to the tank, but only 1 line from the pump to the TBI.

It's the same pump that was put on a similiar vintage LT1 for my boat.

This pump must have an internal regulator then. If that is the case, the pump from the ford truck or van that Jake mentioned will not work for the TBI system. I guess I am not all that familiar with that system. Is that just one big injector at the throttle body? I guess if that is what the general used, that might be what you are stuck with.
